Plastic Logic is a leading developer of plastic electronics technology. The technology has

the potential to revolutionize new applications by printing electronics on thin and flexible

plastic substrates using a process scaleable for large area, high volume and low cost.

Plastic Logic is developing and exploiting world-class technology for manufacturing printedplastic electronic circuits. These circuits areconstructed using solution processing and direct-write techniques and consist of transistors andother components that are produced frompolymers and a variety of other materials.

Low processing temperatures allowing the use of flexible and low-cost plastic

substrates.

Eventual migration from sheet-based to roll-to-roll processing.

This approach enables active electronic circuits to be produced on large flexible plasticsubstrates with high yield. In addition, direct-write techniques provide the potential forrapid design cycles and customization, shorter run-lengths and faster turn-around.

This is achieved without the complexity and capital expense of:

\u2022

Multiple mask steps requiring precision alignment

\u2022

High temperature processing

\u2022

Flexible Displays

Plastic Logic is developing licensable manufacturing solutions for printing thin andflexible active-matrix displays. When combined with an electronic-paper imaging film,Plastic Logic's backplane technology enables highly portable, readable and powerefficient displays. The initial application focus is e-readers (e.g. e-books, e-dictionaries,e-maps, e-newspapers). These displays will often be wirelessly connected to WANdevices such mobile phones and PDAs, allowing users to access content 'on-the-move'more comfortably and efficiently than is possible using a small integrated display.

This is the first step towards flexible and plastic backplanes for a range of display

High information content displays, such as those found in laptops, PDAs and high-endmobile phones, require an active matrix to achieve high resolution and superior front-of-screen performance. In an active matrix system, the appearance of each dot on the displayis controlled with at least one transistor (TFT). In color displays, each picture element(pixel) is normally made up of three dots (or sub-pixels), one each for red, green andblue. An active matrix display therefore requires a very large array of transistors to befabricated (a color VGA display consists of about 1 million sub-pixels). Today, theseTFTs are fabricated in amorphous silicon using a complex and capital intensive process.The array of TFTs which drive the display is referred to as the backplane and the displayeffect which it switches is referred to as the front-plane (e.g. Liquid Crystal, ElectronicImaging Film (e-paper), OLED).

A flexible backplane has long been the missing component in producing high informationcontent flexible displays. Using its unique plastic electronics technology, Plastic Logic isdeveloping the first manufacturable cost-effective solution to this problem.
